If the problem is caused by imported data, consider correcting it in the original
software and re-importing it into Revit Architecture.
Problem: Revit Architecture failed to regenerate the ceiling geometry upon ex-
ecuting your last action.
Solution: You cannot ignore this command. You need to cancel it. This error
might occur if you have sketched an opening in a ceiling and then locked that
opening to another element, such as a wall. If you move the wall, the opening
moves with it. If the opening should suddenly lose its host (the ceiling), this error
would appear. You can edit the ceiling sketch and then attempt the command
again.
Problem: Revit Architecture failed to regenerate the floor geometry upon executing
your last action.
Solution: You cannot ignore this command. You need to cancel it. This error
might occur if you have sketched an opening in a floor and then locked that
opening to another element, such as a wall. If you move the wall, the opening
moves with it. If the opening should suddenly lose its host (the floor), this error
would appear. You can edit the floor sketch and then attempt the command
again.
Problem: Revit Architecture cannot regenerate the geometry to display the moved
model component.
Solution: If you move a door or a window, or other such wall-hosted components,
in such a way that Revit Architecture cannot regenerate the geometry properly,
this message appears. This might happen if you move a window onto a door in
a plan view; Revit Architecture cannot cut both a door instance and a window
instance simultaneously. The error might also occur if you move a component
outside a wall, by either dragging the component, or shortening the wall such
that it cannot host the component. You can either cancel the move or delete the
particular instance. Note that [component] is a variable for the particular instance:
for example, a 36"X80" door.
Problem: While creating a family, you have tried to make a reference dimension
constraining.
Solution: You cannot turn a reference dimension into a constraint.
Problem: Revit Architecture prevents you from accidentally drawing the element,
typically a wall, reference plane, or line, if it is less than 1mm on the screen.
Solution: If you intend to make the element that small, zoom in the view.
Details
Problem: You had a workset editable by you in this local file. Another user has
replaced the central file with a previous backup copy, where the workset you are
editing either does not exist or has a previous version.
Solution: Find out why the central file was restored. If it must stay restored, you
have to redo your changes, again by making another local copy. You can copy
elements from your current local copy if that is helpful.
